《义务教育数学课程标准(2011版)》明确指出:学生要经历图形的抽象、分类、性质探讨等过程,掌握图形与几何的基础知识和技能,初步形成几何直观,发展形象思维和抽象思维,在参与观察、实验、猜想、证明等数学活动中发展合情推理和演绎推理能力.本文从圆周角的性质探讨体现“过程”的教学策略,与各位同仁作一讨论交流.
The Compulsory Education Mathematics Curriculum Standard (2011 Edition) clearly states that students should go through the process of abstraction, classification and nature exploration of graphics, master the basic knowledge and skills of graphics and geometry, initially form the geometric intuition, develop the image thinking and abstract thinking, In the participation of observation, experiment, conjecture, proof and other mathematical activities in the development of sentimental reasoning and deductive reasoning ability.This paper from the angle of the nature of the circle to reflect “process ” teaching strategy, and colleagues to discuss and exchange.
